The ADF7021 takes the performance beyond that of the ADF7020 with Rx sensitivity increased to -123dBm at 1kbps or -130dBm at 100bps. The ADF7021 has improved AFC performance and the power amplifier or PA meets the new ETSI specification for avoiding transient spurs when turning on/off. The device also supports FCC Part 90 in the USA, ETSI EN300-220 in Europe, ARIB STD-T67 in Japan as well as the Chinese & Korean Standards.
